FNB connect simcard

I was sold to use the FNB connect simcard, this required me to port from my previous network to the FNB connect one, at the time it seemed like a good idea. During the usage I'd get complete no service from the sim card and after days of calling and getting no help the service came back, now again it there's no service, the enquiry centre is of no help I was told to visit a branch to get this resolved I did exactly that. The staff was really not interested, I was on the phone with a consultant who sounded like she didn't know half of what she was saying or doing. I went back with a simcard of no service, called again hoping for some assistance it was the same story, they told me to return to the branch after the last time, I'm not exactly looking forward to the experience of not getting help.
